claims.

This invention pertains in'general to commodity packaging andspecifically relates to a form of combined cover and package structure.

One cf the objects of my invention consists in providing a packageconstruction of sheets of different size for producing a package havingacover ani/or indicia-sheet. l

Another object of my invention comprises producing a package structurefabricated of sheets of diilering material.

A further object consists in providing a composite package structurehaving a flexible extending cover portion contiguous with separablyattached sealed commodity` enclosure portions... These and other objectswill be apparent from `the following, reference being had to theaccompanying drawing in which like reference numerals designatecorresponding parts throughout, and in which:

Fig. 1 is a top plan view of one embodiment of the package structure ofmy invention in an extended position With the cover open;

Fig. 2 is an enlarged side view of the representation of Fig l;

Fig. 4 is a side view of the representation of Fig. 3.

My invention contemplates the provision of a commodity-containingpackage structure particularly characterized in ease of fabrication andinexpensive construction. This package consists of a plurality of sealedcommodity-containing enclosures and an accompanying indicia instructionand cover sheet embraced in a compact and unitary package structurecomposed of a minimum amount of package material and made with a minimumof manufacturing operations. In the construction of a preferredembodiment of this package, I provide a pair of sheets of packagingmaterial, one sheet being substantially twice the area of the other.These two sheets are bound together in a single operation of packing andheat crimping processing to form a plurality of separate individuallysealed commodity-containing enclosures retained by a common bindingstructure but separable therefrom for individual use. At the same time,an extending portion of one of the sheets serves as a cover andinstructionvsheet which is permanently associated with the bindingstructure to be retained until the package as a whole is completely usedand discarded. One y of the features resides in-that the cover sheetwhich forms part of the package structure proper is composed of amaterial especially suited to (c1. zoe-'56) printing and differs fromthe material used in the remainder of the package. Although I show onlytwo sheets in my present disclosure, it will be recognized that this is`merely for purposes of illustration and that various numbers of sheetsof various or similar materials can be employed without departing fromthe intended scope of my invention.

Referring to the drawing in detail, and particularly to Figs. v1 and 2,there is provided a lo sheet of coated viscose material I and anothersheet of coated material 2. The sheet of material I may be composed ofwhat is commercially known as cellophane, while the sheet 2 may becomposed of transparent paper which may have 15 a heat treatment coatingthereon. This paper is especially adapted for receiving and retainingprinted impressions. The sheets I and 2 are bonded together in aninterdigitating heat treatment to form a plurality of squares eachhaving n centrally positioned circular commodity-containing recesses l,5, and 6. 'I'he coating on the sheets I and 2 is melted during the heatprocess and the structure of the sheets is changed in crimped areas tobecome embrittled and more 25 susceptible to tearing than the areaswhich are not thus treated. 'i

An area 0" of interdigitated heat treated bond is provided extendingalong and adjacentthe squares having the recesses- 4, 5, and 6, as willbe 30 apparent from the figures. This area serves as a permanent bindingfor the package as a whole. Between the area "C and the squares havingthe recesses 4, 5, and 6, there is provided an area d in which nocrimping occurs and which is co- 35 extensive with the binding area C.This-area serves as a guide line to guide the tearing of the embrittledcrimped areas in the removal of an article contained within one of therecesses 4, 5, or 6.v Other guide line areas, one of which is desoignated at f, extend perpendicular to the guide line-represented by thearea d, and separate the squares having the recesses l, 5, and 6 as willbe apparent from Fig. 1. Further guide lines, represented by the arease, extend from the 45 -outside of each of the squares internally of thecommodity-containing enclosures or recesses therein. In accordance withthe principles of my invention, the two sheets 'I and 2 are perforatedat points indicated at 8, 9, and I0 to` form a sep- 50 yarableconnection for the squares so that they pharmaceutical article such as apill,` and the exrepresented'by C"., The extending portion I2 of thesheet! isloldedalong the line G and serves as a cover fothe package aswell as for indicia purposes. Figs.l 3 andl4 show the appearance of thepackage when the ,extending DOrtion I! of sheet I-is folded-over toserve as a cover indicia sheet. Upon this extending portion I2 oi!ysheet I' various printed instructions and/or ad.

vertisements canl be placed inasmuch as the material of this sheet isparticularly adapted for receiving and retaining'such printed indicia.-

Various articles may be placed within the co1n.V modityecontainingrecesses. For example, the receases l, l, and I may'each be suppliedwith a tended portion I2 of the sheet 2 provided with dosageinstructions for the use of these pills. The consumer may then removethe individual squares and the individual pills from each recess fromtime to time as required by th'instructions on une extending coverportion i2 of the sheet l. n

will be seen therefore that the packagefas a whole ease. It will berecognized that this form of package structure is particularly welladapted for high speed package manufacturing since the entire packagingoperation can be accomplished in a continuous strip-feeding process.

Although I have shown al single line of squares for commodity-containingrecesses therein, it will be recognized that several lines of suchsquares can be provided as well as additional sheets without departingfrom the intended scope of my invention. Further, various forms ofmaterial may be used for the sheet 2, such as metal foils and the like.When the sheet 2 is composed of a metal foil the package has a'strikingappearance and the enclosed articles are still visible through thetransparent sheet i. Such forms of package structure are clearly withinthe intended scope of my invention. I do not therefore desire to limit2,069,838 l myself to any special details except as pointed out in theappended claims. I claimt@ 1. A package structure composed of opposedflayers of lsheet material of unequal .width interdigitated yto i'orm 'aplurality' -of commodity-containing separably inter-joined envelopeportions,

ing envelope portions to'form a cover for said'y commodity-containingenvelope portions, said en- \velope portions being individuallydetachable without mutilation of said cover.l

2.' .A package structure, in accordance with claim lrincluding a commonbinding ridge extending between said cover and said envelope portionsfand to which said commodity-containing envelope portions are separablyjoined for individuall ,removal therefrom.

3. AA 4package* structure in accordance with claim 1 in which saidopposed layers are of different materials. the narrower of which istransparent and the other of which is especially adapted for receivingand retaining printed indicia.

4. As a. new article of manufacture, a package structure composed ofopposed layers of coated viscose material, one of said layers beingsubstantially twice the width of the other layer, they narrower of saidlayers being interdigitated with the other ofv said layers to form aseries of commodity-containing envelope portions as well as aninterdigitated bonding yridge extending along said commodity-containingenvelope portions and between said portions and the extending area ofsaid Wider layer to serve as a binding and fold-over ridge portioncentrally disposed of said wider layer whereby said extending area mayserve as a,

cover and indicia sheet for said commodity-containing envelope portions.

5. A package structure in accordance with claim 4 in which saidcommodity-containing envelope portions are bounded by perforated areasand guide lines for facilitating the directed tearing of theinterdigitated areas of said material.
